68260807 ÷ 454 
We want to divide 68260807 by 454.

On to step 1:
6 divided by 454 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 454

Advancing to step 2:
The number 454 fits into 68 0 times, leaving a remainder of 68.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 454

Going ahead to step 3:
When dividing 682 by 454, we get 1 with a remainder of 228.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 454 from 682 to get 228.
Append the next digit (6) from the dividend to 228 and continue with: 2286 / 454

Moving on to step 4:
If we divide 2286 by 454, we get 5 and a remainder of 16.
Write down 5 as next digit of the result. 
Result so far: 15.0
The remainder is 16 after subtracting 2270 from 2286.
Take the next digit (0) from the dividend and append it to 16, then repeat: 160 / 454

Step 5:
454 goes into 160 0 times with a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 150.0
The remainder is 160 after subtracting 0 from 160.
Bring next digit (8) of the dividend behind the 160 and repeat the process: 1608 / 454

Let's proceed to step 6:
454 can be fit into 1608 3 times, resulting in a remainder of 246.
The number 3 becomes the next digit in our result. 
Result so far: 1503.0
If we take 1362 away from 1608, we end up with 246.
Bring next digit (0) of the dividend behind the 246 and repeat the process: 2460 / 454

Advancing to step 7:
The number 454 fits into 2460 5 times, leaving a remainder of 190.
The number 5 becomes the next digit in our result. 
Result so far: 15035.0
Subtract 2270 from 2460 to get 190.
Grab the next digit (7) from the dividend, add it to 190, then carry on: 1907 / 454

On to step 8:
1907 divided by 454 is 4 with a remainder of 91.
Put 4 as the next digit of the answer. 
Result so far: 150354.0
If we take 1816 away from 1907, we end up with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

Going ahead to step 9:
If we divide 910 by 454, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 150354.2
Deduct 908 from 910 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
The number 454 fits into 20 0 times, leaving a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 150354.2
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
200 divided by 454 is 0 with a remainder of 200.
The next digit of our result is 0. 
Result so far: 150354.2
If we subtract 0 from 200, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 150354.2 with a balance of 0.02.
